It is possible also to manage mailing lists subscribtions simply by emails, to send personalized messages with the user name and to schedule delays up to 24h (86400 secs); all this also from command-line. Since it is developed in Java it is a cross-platform application and does not need installation but needs only the Java Virtual Machine (version 6 or higher) that, in the case, is very easy to download and install.
